Trevor Rose’s Insights - Trevor’s most-liked answers from 5i Research. The Crushing Power of Interest Rates. Central Banks largely have one tool that they can use to curb excess demand, and therefore inflation, which is interest rates. Increasing interest rates cause economic demand to slow and decreasing interest rates are used to stimulate the economy. The Federal Reserve has historically raised interest rates when the labour market is strong and decreased interest rates when it is weak. As we know from this market update so far, the labour market is quite strong, which is why the Fed is comfortable with increasing rates, particularly at such a rapid pace. While many, including the Fed, are quite worried that a stubbornly tight labour market may keep inflation high for years, what we know from recent history is that rising interest rates have demonstrated their ability to dismantle a strong labour market.
